KLH Audio has introduced the Model Four, a new addition to its acclaimed Model Collection, making its debut at HIGH END Vienna 2026. Priced at $1,999 per pair, the Model Four is a slim 8-inch three-way acoustic suspension loudspeaker that bridges the gap between the Model Three and Model Five, delivering full-range performance in a highly placement-friendly cabinet designed for today’s homes.
The Next Chapter in the Model Collection
KLH has carefully expanded its Model Collection since the successful reintroduction of the Model Five in 2021. The Model Three brought acoustic suspension excellence to a compact bookshelf design, while the Model Seven delivered flagship three-way performance with a massive 13-inch woofer in a narrow cabinet.
The new KLH Model Four combines the best attributes of these models: the 8-inch woofer from the Model Three paired with the midrange, tweeter, and crossover architecture of the Model Five. The result is a refined, full-range loudspeaker with exceptional vocal presence, midrange clarity, and high-frequency detail in a space-efficient form factor.
Built for Design-Conscious Listeners and Real Rooms
Modern listening environments — apartments, lofts, and living rooms — demand loudspeakers that perform well without dominating the space. The Model Four addresses this need with a wide 13-inch baffle and shallow 8.25-inch cabinet depth, making it the slimmest floorstander in the Model Collection.
Thanks to its acoustic suspension design, the Model Four delivers tight, accurate bass even when placed close to walls, eliminating the placement challenges common with ported designs. It includes a purpose-built 6-degree slanted riser base that aligns the drivers perfectly with the listener while keeping total depth under 11 inches.
This room-friendly approach, combined with classic mid-century modern aesthetics, makes the Model Four ideal for listeners who want high-fidelity sound without compromising interior design.
A Dedicated Midrange Driver Completes the Sonic Story
The Model Four features a true three-way sealed system housed in a structurally reinforced MDF enclosure. An 8-inch pulp-paper cone woofer reaches down to 46Hz, supported by a dedicated 4-inch pulp-paper cone midrange and a 1-inch aluminum dome tweeter. A three-position Acoustic Balance Control switch — a signature KLH feature — allows fine-tuning of the mid and high frequencies to match room acoustics.
“Model Four represents exactly where KLH is headed: honoring the acoustic principles that made this brand stand out while designing products for how people actually live and listen today,” said KLH Audio CEO Scott Hagen. “This is not a bookshelf speaker, nor is it simply a smaller Model Five. It is a distinctive, full-range acoustic-suspension loudspeaker, meticulously built to deliver the natural, controlled and room-friendly sound that defines KLH in a form that fits more homes, rooms and listeners.”
